/* Upper case letters in the instruction names here are macros.
 'A' => print 'b' if no register operands or suffix_always is true
 'B' => print 'b' if suffix_always is true
 'C' => print 's' or 'l' ('w' or 'd' in Intel mode) depending on operand
 .      size prefix
 'D' => print 'w' if no register operands or 'w', 'l' or 'q', if
 .      suffix_always is true
 'E' => print 'e' if 32-bit form of jcxz
 'F' => print 'w' or 'l' depending on address size prefix (loop insns)
 'G' => print 'w' or 'l' depending on operand size prefix (i/o insns)
 'H' => print ",pt" or ",pn" branch hint
 'I' => honor following macro letter even in Intel mode (implemented only
 .      for some of the macro letters)
 'J' => print 'l'
 'K' => print 'd' or 'q' if rex prefix is present.
 'L' => print 'l' if suffix_always is true
 'N' => print 'n' if instruction has no wait "prefix"
 'O' => print 'd' or 'o' (or 'q' in Intel mode)
 'P' => print 'w', 'l' or 'q' if instruction has an operand size prefix,
 .      or suffix_always is true.  print 'q' if rex prefix is present.
 'Q' => print 'w', 'l' or 'q' if no register operands or suffix_always
 .      is true
 'R' => print 'w', 'l' or 'q' ('d' for 'l' and 'e' in Intel mode)
 'S' => print 'w', 'l' or 'q' if suffix_always is true
 'T' => print 'q' in 64bit mode and behave as 'P' otherwise
 'U' => print 'q' in 64bit mode and behave as 'Q' otherwise
 'V' => print 'q' in 64bit mode and behave as 'S' otherwise
 'W' => print 'b', 'w' or 'l' ('d' in Intel mode)
 'X' => print 's', 'd' depending on data16 prefix (for XMM)
 'Y' => 'q' if instruction has an REX 64bit overwrite prefix
 'Z' => print 'q' in 64bit mode and behave as 'L' otherwise

 Many of the above letters print nothing in Intel mode.  See "putop"
 for the details.

 Braces '{' and '}', and vertical bars '|', indicate alternative
 mnemonic strings for AT&T, Intel, X86_64 AT&T, and X86_64 Intel
 modes.  In cases where there are only two alternatives, the X86_64
 instruction is reserved, and "(bad)" is printed.
